Some minerals are fortunate, either for the time they were discovered, or by the circumstances of their discovery or even by the place where they were found and beyond their greater or lesser beauty, of having become true myths of mineralogy. This is what happens with the Grandidierite of which, in addition, recent discoveries of an exceptional quality have been made to date, as is the case with this splendid individual flattened crystal with faces and edges unusually sharp and with the top termination very well defined while the lower termination is polycrystalline and somewhat rough. The crystal is bright, between transparent and translucent and it has a very deep and uniform bluish-green color.

Very sharp flattened and complete crystal (on the base it has small fragments of a feldspar matrix) with very well defined faces and edges and a perfect termination, slightly rough but free of damage. It is translucent and has a very deep and uniform bluish-green color. Among the best for this very rare species, a classic from Madagascar.

Grandidierite is one of the great myths of mineralogy, especially in the field of rare species. It was believed that we would never see more Grandidierites of such quality as those that exist in the great museums of the world, especially the museums of Paris, but for a couple of years in a little-known Madagascar site excellent Grandidierites have been appearing, some of them of as great quality as the famous specimens that appeared in the past.This specimen was photographed for the ‘Munich 2017’ section of the magazine ‘Mineralien Welt’ and appears on page 70 of number 1/2018, and for the magazine ‘Mineralogical Record’ on page 338 in the volume 49, number 2

Specimen size: 5.4 × 2.8 × 2.9 cm = 2.1” × 1.1” × 1.1”

Group of Grandidierite crystals on matrix, one of them clearly dominant and very large for the species. The crystals, unusually well defined, are translucent and have a uniform and intense bluish-green color. The main crystal has a rough termination but it is complete, as the detailed image shows. The sample has great quality for this rare silicate.
